To'aZZ who-m t may concern: Y. .Be i-t known that I', THOMAS BnUoUs, a

citizen ofl the United States of America, re'- ysiding at Cedar Springs, in the vcounty of following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art vto which it appertains to make and use the same.

My invention relates to improvements in carbureters, and more particularly to cabureters for use in connection with internal combustionl engines, and its object is to simplify the construction; to provide `an automatic valve to control the flow of fuel and to stop oli' the same when the device is out of operation, and to provide the device with various new and useful features, as'hereinafter more fully described and particularly pointed out in the claims.

. My invention consists essentially of a valve to control the iowv of` fuel opened by the air current flowingthrough theI device and automatically closed when-the device is out yof operation; means for limiting:V the opening of said valve connected to the throtto a` greaterv orless' extent, and in various features Vof construction and arrangement as will more fully appear by reference to the e accompanying d 'r'awings,'1n which FigureV 1 is a vertical section of a device embodying my invention, shownl aswhen out of operation; Fig. 2 an enlarged detail showing the fuel valve opened to a moderate extent; and Fig. 3 the same with the fuel `valve `opened to a greater extent. v

Likel numbers referto like parts in all of the figures.

1 represents a. cylindrical case having a verticall axis; 2 a lateral air inlet atthe bottom; of thecase; 3 a throttle valve to control the airfinlet and direct the air downward to the bottom of the case. Y

4 is alateral inlet at' the bottom of the case fo influx'of fuel; 5 isfa needle-valve to limit the 'flow of fuel, above which valve,

arranged in the ax'is of the case and rojecting upward within the lower part o the same 1s a nozzle 6, within which is avertically movable pin or needle 7, the upper part having a greater diameter than the lower part, whereby as the needle is raisedthe oh-l Specification of Letters Patent.

struction of the nozzle is reduced to permit i increased. `flow of fluid from the nozzle. Thispin is carried by a disk Shaving a cone valve where the pin joins the same, which valve closes the nozzle outright when no air isV goingf through and the diskrests on the end of the nozzle.

9 is a stemv extending upward from the disk to guide the same and the pin in their vertical movement. .This stem is slidable freely in a vertically adjustable sleeve 10 mountedv in the axis of a slide 11 vertically movable in a tubular housing 14 fitting within the case 1, and vertically adjustable there- `in. This housing has a conical bottom, the 4lower end of which is contracted to about the diameter of the disk 8 and surrounds the upper end of the nozzle 7. Extending downward around the nozzle is a conical extension of the housing forming the lowerl end of the housing and terminating at a distance from the baseof the nozzle whereby the airis directed against theunder'side of thefdisk as it passes upward through the housing. The slide 11 is connected by a rod' v121:0 a throttle valve 13 located in the top of the-case, whereby as the throttle valve 'is opened and' closed the slide is simultathrou h the'device the higher the disk 8 will rlse and the slide 11 will also be raised' by opening *the throttle valve to permit of this movementof the disk. The fuel is also 'permitted to iow in greater quantity by the withdrawal of the pin 7 more or less from-within the nozzle, thusreducing the A obstruction therein.

. The jet of fuel from the nozzle is divided .the pin and valveand turned outward radially over the under surface of the disk 8 against which the 'air is directed. The radial movement of the fuel thus spreads and thins it and the current of air intimately -mingles therewith. Themixture then passes l upward through the housing and throttle 4ing a valve to close the nozzle,

What I claim Iis: 1. A carbureter, comprising a cylindrical case, lateral fuel-and air inlets at the bottom of the case, a nozzle projecting upwardl from the bottom of the case and in the axis of the same, a housing surrounding the nozzle and adjustable in' the case, a dlsk carrya needle projecting within the nozzle, and means limiting the upward movement the disk.

nozzle,

2. A carbureter, comprising a vertically disposed cylindrical case having an air inlet in the bottom thereof, a throttle valve in the upperpart of the case, a fuel nozzle projectin from the bottom of the case and in the axi of the same, a housing vertically adjustable in the-case and having oppositely extended conical portions surrounding the a valve to close the nozzle, a needle of various diameters to obstruct the nozzle, a disk carrying the needle and valve, a stem to the disk, an adjustable sleeve for the stem, ,aslide adjustable in the housing and carrying` the sleeve, and means for connect-l housing disposed within said casing and having oppositely flared inner walls, means for ad justably mounting said housing in the casing, a throttle valve in said casing, a

for

lin the upper end thereof,

slide disposed within the housing and operatively connected to the throttle valve, a needle valve of variable area disposed vWithin the' nozzle in 'axial alinement with the before-mentioned needle valve, a disk carried by the second-mentioned needle valve and disposed above the nozzle and limited in its movement by the slide and a stem extending from the needle valve and carrying the disk.

4. In a carbureter, a casing having an air inlet and a4 fuel nozzle in the lower end thereof and a throttle valve in the upper end thereof, a slide disposed therein, said slide having a sleeve threaded in the opening of the slide, a valve controlling the fuel nozzle, a stem extending from the. valve and posed in said sleeve, and an operative connection between the throttle valve and slide.

5. The combination in a carbureter,- ofa casing having an air inlet and a fuel nozzle in theV lower end thereof and a throttle valve adjustable in said casing, said movablemember, said slide having 'a central threaded sleeve formed therein, a second sleeve threaded in saidrst sleeve, a valve stem movable in lsaid second mentioned sleeve, a valve carried by said valve.

stem for engagement with the second mentioned sleeve lwhereby the movement of said valve will be limited and an operative conf nection between the lthrottle valve and` slide.

In testimony whereof I affix my signature in presence of two witnesses.
